Atco Rubber Products 031 6 Flexible Duct Metalized R-8 6 in

Product Description

The ATCO RUBBER PRODUCTS 031 6 is a metalized flexible duct with an R-8 insulation rating, designed for use in residential and light commercial HVAC air distribution systems. The 6-inch diameter construction features a metalized outer jacket that provides a vapor barrier and helps protect the insulation core during installation and long-term service. HVAC installers use this flex duct to connect air handlers, plenums, and diffusers where rigid sheet metal ductwork is impractical or where routing requires flexibility.

This flex duct is well suited for attic, crawlspace, and conditioned-space installations where R-8 insulation is required by code. Many jurisdictions mandate a minimum of R-8 on flex duct in unconditioned spaces, making this product a code-compliant choice for new construction and retrofit work. The metalized jacket is compatible with standard flex duct saddle clamps, duct tape rated for duct systems, and drawband connectors used throughout the trade.

Key Features

• R-8 insulation value meets common code requirements for flex duct in unconditioned spaces
• 6-inch diameter fits standard collar sizes on registers, boots, and air handlers
• Metalized outer jacket provides vapor barrier protection and reflects radiant heat
• Flexible construction allows routing around obstructions without rigid fittings
• Compatible with standard drawbands, clamps, and mastic or UL 181-rated tape connections

Compatibility

Designed as an OEM-style replacement and new-installation flexible duct for residential and light commercial HVAC air distribution systems using 6-inch duct collars and fittings.

Installation Notes

Installation should be performed by a qualified HVAC technician in accordance with ACCA Manual D, local mechanical codes, and the duct manufacturer guidelines. Power down the air handler and close the system before making duct connections. Avoid sharp bends that reduce effective airflow area — keep bend radii as gradual as possible and fully extend the duct to minimize pressure drop. Seal all connections with UL 181-rated drawbands and mastic or listed tape; do not rely on friction fit alone.
